The invention relates to a storage container (1) for a device for automated dispensing of individual portions of medication. Corresponding devices are used in large numbers for blister dispensers and a main problem during use of these containers regards among other things the separation of contaminant particles which arise. To reduce loading with these particles the storage container according to the invention comprises a housing (3a 3b 3c 3d 3e) enclosing a receiving chamber (2) the housing having a bottom surface (4) a separation device (100) arranged on the bottom surface (4) having at least one channel (102) for receiving at least one portion of medication wherein the at least one channel (102) has an opening (103) facing the receiving chamber (2) and an opening (104) facing the bottom surface (4) wherein a contact region (10) arranged on the bottom surface (4) is assigned to the opening (104) facing the bottom surface (4) via which contact surface the portions of medication are guided during a movement of the separation device (100) and at least one recess (7) arranged in the bottom surface (4) outside of the contact surface (10) for receiving contaminant particles present in the container.
